It is a 3 hour time span or difference as 11 am-12 pm is 1 hour, 12 pm-1 pm is another hour, and 1pm-2 pm is a 3rd.
2:00 PM
xy=-50 x+y=2, so y=2-x Substitute y=2-x to xy=-50 x(2-x)=-50 2x-x2=-50 -x2+2x+50=0 x2-2x-50=0 cannot be factorised. So use the abc formula ax2+bx+c=0 a=1, b=-2, c=-50, pm=plus minus, v=square root x=[-b pm v(b2-4ac)]/2a x=[2 pm v(4-4.1.-50)]/2.1 x=[2 pm v(204)]/2 x= [2 pm 2v(51)]/2 x=1 pm v(51) so the answer is 1+v51 and 1-v51 or in decimal (approx): 8.1414 and -6.1414
Time = Distance/Speed = 250km/120kph = 2.0833... hours or 2 hours and 5 minutes.
Just convert the 2 hours to minutes. Then you have the ratio:24 minutes : (the equivalent of 2 hours) Which, if you wish, you can then simplify.
30 minutes is 1/4 of 2 hours
11 am to 11 pm is 12 hours and then add 2 more hours to get 14
2 hours
20
11- 9 = 2, so 2 hours.
2 hours
7 and a half hours
2 hours.

9 am to 12 pm: 3 hours 12 pm to 2:30 pm: 2 1/2 hours 3 + 2 1/2 = 5 1/2 hours. So there are 5 1/2 hours between 9 am and 2:30 pm.
There are 2+12k hours where k is an integer.
There are 17 hours between 2 am and 7 pm.
Three Hours Ain't It?
